The state of Qin used to be a vassal state in the Zhou Dynasty. Its ancestor Boyi had helped Dayu in flood control. He was given the surname Ying by Emperor Shun. Feizi, a descendant of Boyi, once raised horses for King Xiaowang of Zhou. With his ability, horses multiplied rapidly. King Xiaowang of Zhou granted him a belt of Qingu (southwest of Tianshui City, Gansu Province). This is the origin of "Qin".
In 770 BC, Duke Xianggong of Qin escorted King Ping of Zhou to Luoyi, where he was granted the title of vassal. Qin founded the country and occupied the territory of the royal family of the Eastern Zhou Dynasty in Guanzhong.
From 230 B.C. to 221 B.C., Ying Zheng, the first emperor of Qin Dynasty, successively destroyed the six states in Guandong, completed the national unification, and then attacked Xiongnu in the north and Baiyue in the south. A series of new policies were adopted in politics, military affairs, economy, transportation, culture and foreign development, which greatly strengthened the unity of the whole country and had a great influence on later generations.
The territory of Qin Dynasty
In the 25th year of the first emperor of Qin Dynasty (222 BC), that is, the year before the unification of the six countries, Minyue and Dongou were merged in the southeast, and Minzhong county was established, which includes Fujian Province and the southeast of Zhejiang Province.
In the 33rd year (214 BC), Wuling in the South and Nanyue in the south, Guilin, Nanhai and Xiang counties were set up, which is equivalent to the two provinces of Guangdong and Guangxi. In the north, Xiongnu was driven to the north, and the Hetao area was set up as Jiuyuan county. As a result, the great wall of Yan, Zhao and Qin in the Warring States period was rebuilt and connected to form the great wall of Qin, which extends from Lintao to Liaodong.
According to historical records, the territory at that time was as follows: "to the sea and Korea in the East, to Lintao and Qiangzhong in the west, to beixianghu in the South (to the south of the Tropic of cancer), to Sai in the north, and to Liaodong in Yinshan."
The territory of the Qin Dynasty reached the south of the Yangtze River valley after the merger of the six states. At the beginning of the Qin Dynasty, it attacked the Xiongnu in the north and dispatched Tu Sui to lead 500000 Qin troops to the south of the five ridges to pacify the Baiyue people. The territory of the Qin Dynasty expanded rapidly, reaching about 3.2 million square kilometers. The territory of the Qin Dynasty was roughly as follows: Liaodong in the East, Gansu and Sichuan in the west, Yinshan in the north, northern and central Vietnam in the south, and Yunnan and Guangxi in the southwest.
East to the sea, West to Lintao, South to Xiangjun, north to the Great Wall.
In addition, the first emperor of Qin Dynasty opened Wuchi road to the southwest, roughly from today's Yibin in Sichuan to Qujing in Yunnan. He controlled the local tribal countries and extended political power into the Yunnan Guizhou Plateau,

That is to say, it reaches Dahai in the East, Gansu in the west, Ordos in the north and central Vietnam in the south.
According to the records, after Qin Shihuang unified the Central Plains, he sent troops to take Luliang, set up Guilin, Nanhai and Xiangjun, sent Mengtian to attack Xiongnu, and took "Henan". Therefore, the above territory should be the scope of Qin Dynasty after the territory was basically stable.
